Germany is facing heightened security alerts due to Islamist terror threats. Over the last five years, authorities have seen younger perpetrators, new online spaces for radicalization, and new targets. Attackers are using familiar methods of attack and declaring support to well-known groups such as the Islamic State.

TRAVEL BAN
This travel ban, like the earlier ones, will not significantly improve national security and public safety in the United States. That’s because migrants account for a minuscule portion of violence in the U.S. And migrants from the latest travel ban countries account for an even smaller portion.

TRAVEL BAN
The US government has a responsibility to keep terrorists and criminals out of the country and to remove those who make it through. But the government should pursue a rational and evidence-based approach when evaluating the threat posed by foreign nationals. The Trump administration has banned large swaths of travelers and immigrants from many countries based on evidence that it likely won’t release and, if it does, will likely raise more questions than answers.

EXTREMISM
Reactions to the Boulder, Colorado attack followed a familiar pattern to the 21 May 2025 Washington, D.C. murder of a couple leaving an event for young Jewish. Many of the same anti-Zionist groups and influencers who celebrated or justified D.C. shooting suspect Elias Rodriguez’s actions reacted similarly to the Boulder attack. other extremists also responded with predictable antisemitism and conspiracy theories by claiming the attack was a “false flag” or blaming Jews.

EXTREMISM
As President Donald Trump guts the main federal office dedicated to preventing terrorism, states say they’re left to take the lead in spotlighting threats. Some state efforts are robust, others are fledgling, and yet other states are still formalizing strategies for addressing extremism. With the federal government largely retreating from focusing on extremist dangers, prevention advocates say the threat of violent extremism is likely to increase.

ARGUMENT: A KILLER, NOT A TERRORIST
Discretion is crucial to the American tradition of criminal law, Jacob Ware and Ania Zolyniak write, noting that “lawmakers enact broader statutes to empower prosecutors to pursue justice while entrusting that they will stay within the confines of their authority and screen out the inevitable “absurd” cases that may arise.” Discretion is also vital to maintaining the legitimacy of the legal system. In the prosecution’s case against Luigi Mangione, they charge, “That discretion was abused.”

TERRORISM
On the evening of 21 May 2025, shortly after 9:00 pm, Elias Rodriguez, 30, of Chicago, Illinois, allegedly shot and killed two Israeli embassy staff members as they were leaving an AJC (American Jewish Committee) Young Diplomats event at the Capital Jewish Museum in Washington DC. As he was taken into custody, Rodriguez shouted, “Free, free Palestine.” An online manifesto posted on X lays out the reasons for the attack.

TERRORISM
In recent months, there have been a series of vehicular attacks in Germany, the United States, and Israel targeting civilians during celebrations and public gatherings. The relative ease of launching a vehicle attack and the very large number of soft targets available means it is a tactic that is very difficult to defend against.

By leveraging machine learning to produce AI-generated content, adversaries can weaponize synthetic media, making fact and fiction nearly indistinguishable. The death—or not—of combatant leaders is prime example of the magnitude of the challenge this emerging reality poses.

GAIN OF FUNCTION RESEARCH
Last week President Trump signed an executive order which imposes new restrictions on gain-of-function (GoF) research. Scientists and biosecurity experts say it is not unreasonable to review the security measures governing GoF research, but that the administration has used a definition of GoF which is too broad, vague, and inaccurate, raising the concern that the United States will become less safe, and less prepared for unforeseen biothreats, as essential research and important studies would be hobbled because of the wide net cast by the executive order.

TERRORISM
Terrorist attacks are more common during security and economic crises, but they decrease during humanitarian disasters. Perpetrators focus on what we call “ripe moments” – circumstances that present unique opportunities for terrorist groups to attack when the state is distracted or weakened. But the reason why a state may be vulnerable matters to terrorists.

SENSORS

TERRORISM
Politically motivated attacks, carried out by lone individuals lacking direct affiliation with any terrorist group, have become more common in Europe during the last few decades. Lone-actor attacks are difficult to prevent precisely because they are not a systemic threat in the way that coordinated, group-based terrorism can be. Its danger lies in isolated bursts of violence rather than in sustained campaigns. But there are patterns worth following that could help prevent future incidents.

Social extremism is evolving in reach and form. While traditional racial supremacy ideologies remain, contemporary movements are now often fueled by something more personal and emotionally resonant: male grievance.
